I've actually driven mine today
polish, 2 coats of wax and 20 miles later LOADS of tar all over the car. literally dripping off the arches and bumpers so d!ckhead hear is stood with the speed detailer wiping it off in a car park looking the right tool

anyway if you want a shot of the chassis cleaner its no problem. its a bit of a faff but does seem to work.
i rotated my wheels the other day and the suspension parts were still minging though so cleaned them down the old fashioned way while i had the wheels off.
ill bring it over if you want a lend anyway
